There are some experts on the forum that can give you some good "general" harvest advice that will almost certainly be beneficial to your lake.
However, an actual survey of the fish populations will yield even better data to determine the best course of action.
Your group can elect to fund an electrofishing survey. Another option is to get as many of your anglers as possible to submit catch records of length and weight.
There are many Pond Boss "nerds" that love chewing on that kind of information and giving suggestions for your lake.
Sounds like you have a great fishery right now. Good luck on your next step in pond management, and I hope your group continues to break the existing "lake records"!
